COMPCSITION PAINT FOR LEATHER.

\ To all whom/it may concern:

Be it known that I, JOSEPH RICHARD, a British subject, patent-leathermaker, residing at 7 30 Charlevoix street, in the city of Montreal,'inthe Province of Quebec, in the Dominion of Canada, have invented certainnew and useful Improvements in Composition Paint for Leather; and I dohereby declare that the .following is a full, clear, and exactdescription of the same.

The present invention relates to -a composition paint for leather andits main object is to provide a paint which has filling and adhesivequalities whereby time and labor will be saved in tinting the skin, thusreducing considerably the cost of manufacture.

The paint is composed of crude linseed oil which serves as a filler,mixed with benzin and a certain portion of raw umber which serves as asize. To this is added a certain quantity of dry sugar of lead, whichcauses the composition to dry quickly when applied to the leather, towhich is thoroughly mixed prepared paint which has been dilutedbeforehand in benzin.

The following is an approximate proportion of the different ingredientswhich enter into the present invention :-30 gallons of crude linseedoil, 30 gallons of benzin, 16 ounces of raw umber, 4 ounces of dry sugarof lead and 15 gallons of mixed paint diluted in benzin.

The first step in making this composit1on consists in boiling crudelinseed oil,

raw umber and dry sugar of lead until it reaches approximately 600Fahrenheit. It is then left to cool and comes into a thick paste whichis dissolved with benzin until it is mixed with prepared paintpreferably also mixed with benzin.

The method now used to tint leather Specification of Letters Patent.

consists in first putting a coat of filling.

composition which takes a few hours to dry, and then to provide the skinwith 2 or 3 coatings of varnish which, of course, take considerable timeto dry. Over this varnish 1 or 2 coats of mixed paint is put on theskin. This method, of course, takes considerable time and necessitatesskilled labor in order that the different coats of varnish and paint areproperly put on.

Applicants composition paint will eliminate all these operations, andwill give similar results" to the old method and 1 or 2 coatings, at themost, as case may be, of this improved composition is sufficient. A'girl or ordinary laborer can do this without any difficulty. The paintis combined or rather has all the properties necessary to fill the grainof the skin, and adherent for the paint to hold down the leather.

The results obtained are absolutely identical to the results obtainedwith the old will readily be seen that considerable time and money willbe saved in tinting the leather.

What I cla m as my invention is:

1. A composition paint of the character described comprising drying oil,a petroleum distillate, umber, sugar of lead, and mixed paintsubstantially as described.

2. A composition paint of the character described comprising, crudelinseed oil, raw umber and dry sugar of lead mixed with benzin andprepared paint substantially as described. I
